Study on Oil-Water Emulsions Based on Soyabean Phospholipids and Phophatidylinositol as Emusifier with Electrical Conductance

Abstract:

The electrical conductance of oil-water emulsions based on Soyabean phospholipids (PL) and phosphatidylinositol(PI) as emulsifier was determined. Oil/water emulsions were prepared with oil(g):water(g) = 25:75, Tween 80 (0.15%wt), and NaCl (0.02%wt), the amount of PL and PI ranged from 0.1g/100g to 3.5g/100g. The effects of temperature and concentration of NaCl on the emulsion formation for this system were further investigated. As the concentration of Soyabean PL and PI increased from 0.1g/100g to 3.5g/100g, the electrical conductance of the system increased from 4.98 μs/cm to 53.7 μs/cm and 9.30 μs/cm to 96.0μs/cm, respectively. The results show that the stability of emulsion with Soyabean Phosphatidylinositol as emulsifier is higher than the emulsion with Soyabean Phospholipids as emulsifier, and formed O/W emulsion. Temperature and electrolyte (NaCL) has influence on the electrical conductance of the system, the electrical conductance of the emulsion increased with the increase of temperature and NaCl concentration. At the concentration of PI 2.0g/100g, the electrical conductance has a point of inflexion.
